Description

Technical Field

[0001] This utility model relates to the technical field of wind pressure resistance testing of solar panels, and in particular to a wind pressure resistance testing platform for solar equipment. Background Technology

[0002] Wind pressure resistance testing of solar equipment is a key technical assessment method to ensure the long-term stable operation of photovoltaic modules outdoors. Because photovoltaic modules are exposed to complex natural environments for a long time, wind load, as a frequent and difficult-to-predict external force, can easily lead to structural deformation, sealing failure, or even damage to the module. Although wind load is not as severe as extreme disasters such as earthquakes or snow loads, its high-frequency and periodic impacts can accelerate material fatigue, especially in weak parts such as module mounting holes and frames, where stress concentration is likely to occur, leading to failure risks such as microcracks in the cells and breakage of the main grid lines. In addition, as the power and size of photovoltaic modules increase, their wind-exposed area increases, and the alternating load formed by the alternating attraction of the front and rear surfaces under dynamic wind pressure will further aggravate the fatigue damage of the materials. Wind pressure resistance testing verifies the structural strength of the module by simulating static and dynamic wind load conditions.

[0003] However, during the wind pressure resistance test of photovoltaic panels, the lack of an adjustment structure in the test platform resulted in the space inside the test platform remaining unchanged when testing smaller photovoltaic panels, leading to a slow increase in wind pressure and thus reducing the testing efficiency of the photovoltaic panels.

[0025] Example 1

[0026] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a wind pressure testing mechanism 100 to realize wind pressure resistance testing of photovoltaic panels.

[0027] The wind pressure testing mechanism 100 includes a test chamber 101, a door 102 is movably connected to the front of the test chamber 101, a placement plate 103 is fixedly connected to the bottom of the inner wall of the test chamber 101, and an air pump 104 is connected to the top of the test chamber 101.

[0028] Specifically, the air pump 104 is started to draw outside air into the test chamber 101 to simulate wind pressure.

[0029] Furthermore, after opening the box door 102, placing the photovoltaic panel on top of the placement plate 103, closing the box door 102, and starting the air pump 104 to draw outside air into the test box 101 to simulate wind pressure.

[0030] Example 2

[0031] Reference Figures 1-5 In the second embodiment of this utility model, an adjustment mechanism 200 is provided to adjust the test space.

[0032] The adjustment mechanism 200 includes a bidirectional lead screw 201. The right side of the bidirectional lead screw 201 is movably connected to the rear side of the top right side of the inner wall of the test chamber 101, and the left side of the bidirectional lead screw 201 passes through the rear side of the top left side of the test chamber 101. Space adjustment plates 202 are movably connected to both sides of the top of the placement plate 103. The surface of the space adjustment plate 202 is slidably connected to the inner wall of the test chamber 101. Positioning components 203 are fixedly connected to both sides of the bottom inner side of the space adjustment plate 202, and limit components 204 are fixedly connected to both sides of the bottom bottom of the space adjustment plate 202. The positioning components 203 include a connecting plate 203a. The outer side of the connecting plate 203a is fixedly connected to both sides of the bottom inner side of the space adjustment plate 202. A positioning plate 203b is provided at the bottom of the connecting plate 203a. Springs 203c are fixedly connected to both sides of the top of the positioning plate 203b, and the other end of the springs 203c is fixedly connected to both sides of the bottom bottom of the connecting plate 203a. The fixed connection and limiting component 204 includes a limiting slider 204a, the top of which is fixedly connected to both sides of the bottom of the space adjustment plate 202. Limiting grooves 204b are provided on both sides of the top of the placement plate 103. The inner wall of the limiting groove 204b is slidably connected to the surface of the limiting slider 204a. Guide grooves 203d are provided on both sides of the bottom of the connecting plate 203a. Guide rods 203e are slidably connected to the inner wall of the guide grooves 203d. The bottom of the guide rods 203e is fixedly connected to both sides of the top of the positioning plate 203b. A limiting disk 203f is fixedly connected to the top of the guide rods 203e. The diameter of the limiting disk 203f is larger than the diameter of the inner wall of the guide groove 203d. A handwheel 205 is fixedly connected to the left side of the bidirectional lead screw 201. The inner side of the bottom of the positioning plate 203b is inclined. Anti-slip grooves 206 are provided on the surface of the handwheel 205. Several anti-slip grooves 206 are provided and are distributed in a ring at equal intervals.

[0033] Specifically, rotating the bidirectional lead screw 201 and utilizing the sliding engagement between the limiting groove 204b and the limiting block can drive the space adjustment plate 202 to move inward, thereby reducing the test space and adapting to the size of the photovoltaic panel. The reduced space allows the air pump 104 to increase the air pressure boosting speed of the test space when it is turned on. When the space adjustment plate 202 moves inward and approaches the photovoltaic panel, the positioning plate 203b applies downward pressure to the photovoltaic panel for positioning.

[0034] Furthermore, after placing the photovoltaic panel, the user first grips the handwheel 205 using the anti-slip groove 206, then rotates the handwheel 205 to drive the bidirectional lead screw 201 to rotate. Utilizing the sliding engagement between the limiting groove 204b and the limiting block, the space adjustment plate 202 can be moved inwards, thereby reducing the test space and adapting to the size of the photovoltaic panel. The reduced space allows for a faster increase in air pressure in the test space when the air pump 104 is turned on. This is achieved as the space adjustment plate 202 moves inwards. When the device moves and approaches the photovoltaic panel, the inner side of the bottom of the positioning plate 203b is inclined, causing the positioning plate 203b to move upward and drive the guide rod 203e to move upward along the guide groove 203d, which compresses the spring 203c. The elastic force of the spring 203c can drive the positioning plate 203b to press down on the photovoltaic panel for positioning. At the same time, the diameter of the limiting plate 203f is larger than the diameter of the inner wall of the guide groove 203d, thereby preventing the guide rod 203e from detaching from the guide groove 203d.

[0035] The remaining structure is the same as that in Example 1.

[0036] Example 3

[0037] Reference Figures 1-5 This is the third embodiment of the present invention, which differs from the second embodiment in that it provides a solar energy equipment wind pressure resistance test bench.

[0038] After opening the box door 102 and placing the photovoltaic panel on top of the placement plate 103, close the box door 102 and start the air pump 104 to draw outside air into the test box 101 to simulate wind pressure. After placing the photovoltaic panel, the user first holds the handwheel 205 through the anti-slip groove 206, and then rotates the handwheel 205 to drive the bidirectional lead screw 201 to rotate. By utilizing the sliding cooperation between the limiting groove 204b and the limiting block, the space adjustment plate 202 can be moved inward, thereby reducing the test space and adapting to the size of the photovoltaic panel. The reduced space allows the air pump 104 to increase the wind pressure boosting speed of the test space when it is turned on.

[0039] When the space adjustment plate 202 moves inward and approaches the photovoltaic panel, the inner side of the bottom of the positioning plate 203b is inclined, causing the positioning plate 203b to move upward and drive the guide rod 203e to move upward along the guide groove 203d, which compresses the spring 203c. The elastic force of the spring 203c can drive the positioning plate 203b to press down on the photovoltaic panel for positioning. At the same time, the diameter of the limiting plate 203f is larger than the diameter of the inner wall of the guide groove 203d, thereby preventing the guide rod 203e from disengaging from the guide groove 203d.

[0040] In summary, during the testing process using the wind pressure testing mechanism 100, the size of the testing space can be adjusted using the adjustment mechanism 200, so that the size of the testing space can be adapted to the size of the photovoltaic panel for testing. The reduced space can increase the wind pressure boosting speed of the testing space when the air pump 104 is turned on.
